輝達股價暴跌:AI晶片警訊?




## Nvidia 股價下跌,因 Super Micro 警告和川普的人工智能貿易政策變動

美國納斯達克上市公司 Nvidia(NVDA)的股價在周三下跌近 4%,原因是投資者對人工智能需求的擔憂和全球晶片市場政策變化的擔憂。

此次股價下跌部分是由於 Nvidia 的重要伺服器合作夥伴 Super Micro Computer(SMCI)發布的令人失望的預測。Super Micro 下調了其第三季度收入和利潤預期,原因是人工智能基礎設施需求放緩。該公司股價暴跌 18%,進一步加劇了對人工智能供應鏈的擔憂。

### 川普政府擬收緊人工智能晶片出口限制

據路透社報導,川普政府正在考慮推翻拜登政府的人工智能晶片出口限制,轉而實施更嚴格的全球許可制度。根據拜登政府的規定,僅有 18 個「第一層」盟國可以自由購買美國製造的人工智能晶片,而約 150 個「第二層」國家,包括印度、以色列和瑞士,則需要特殊許可,而「第三層」國家,如中國和伊朗,則完全被禁止。

擬議的川普政府改革可能會進一步收緊限制,對 Nvidia 的國際增長構成新的壓力。花旗和伯恩斯坦的分析師警告說,這些變化可能會帶來不確定性,並為華為等競爭對手打開大門。

### 市場壓力加大,經濟數據令人擔憂

Nvidia 不是唯一受壓的股票,道瓊斯指數下跌超過 400 點,納斯達克指數下跌近 2%,小盤股終止了六連漲。科技股受到了令人失望的經濟數據的打擊,美國第一季度 GDP 收縮了 0.3%,這是自 COVID-19 疫情初期以來首次經濟衰退。

此外,私人就業數據也令人擔憂,顯示 4 月份僅新增 62,000 個工作崗位,遠低於預期的 125,000 個。市場情緒轉為謹慎,Nvidia 股價跌破了 21 日移動平均線。

### Nvidia 股價未來走勢

儘管周三股價下跌,但 Nvidia 仍然是人工智能競賽中最受關注的玩家之一。然而,地緣政治緊張局勢和不斷變化的貿易規則可能會影響股價的短期走勢。

TD Cowen 分析師指出,新的半導體關稅可能高達 25%,並可能在 7 月份實施,這將進一步給美國晶片製造商帶來壓力。

不過,美國-墨西哥-加拿大貿易協定(USMCA)可能會帶來一些緩解,該協定豁免了 Nvidia 從墨西哥進口的大部分人工智能伺服器。執行長 Jensen Huang 繼續與全球領導人接觸,包括訪問中國、日本和華盛頓特區,以應對日益增長的地緣政治不確定性。

作為編輯,我認為這篇文章揭示了當前科技產業面臨的挑戰和不確定性。Nvidia 股價的下跌反映了投資者對人工智能需求和全球貿易政策變化的擔憂。同時,川普政府擬收緊人工智能晶片出口限制可能會對 Nvidia 的國際增長構成新的壓力。

然而,值得注意的是,Nvidia 仍然是人工智能競賽中最受關注的玩家之一,其長期前景仍然樂觀。投資者需要密切關注相關新聞和市場動態,以做出明智的投資決策。

此外,這篇文章也提醒我們,地緣政治緊張局勢和貿易政策變化可能會對科技產業產生重大影響。投資者需要關注全球經濟和政治局勢的變化,以評估其投資的風險和機會。

總的來說,這篇文章提供了有價值的信息和見解,幫助投資者了解當前科技產業的挑戰和機遇。
